Take the detail and smoothness of the RE-400s, apply a mildly v-shaped signature and you have the Yao Solars/Gratitudes. They are that good.

Also, the best flat cable I've ever used bar none. You'll need to use a cable clip, though, as they're cord-down wear only.

From the Buying Guide, but I think it describes them well:

"If you want something more balanced than the Turbine Pro Copper, but with more bass emphasis and more fun than the Trumpet, then consider my second favorite Monster in-ear, the Monster Gratitude. Inspired by the music of Earth, Wind & Fire (and, of course, endorsed by them), the Gratitude might be the best value in the Monster line, and an outstanding value, period. To my ears, the Gratitude sounds like an evolution of the flagship Monster Turbine Pro models, but can generally be found for a significantly lower price than the Turbine Pro Gold, and far less than the Turbine Pro Copper. To me, the Gratitude is a sign that Monster is stepping up its game, in terms of performance and value."

Yes, Head-fi strikes again. I was not looking for IEMs at all, but I ordered a set at $56.

I Feel your pains..I have way too many In Ears. I barely even use them to be honest. This crap is an evil addiction. But I am a big fan of these monster cable IEMS. They have a good overall package and I feel as if they are collectors items. For instance, I'm a big fan of Miles Davis so I got the tributes and I love Earth Wind and Fire so I had to pull the trigger on these.

I got a pair of Yao Solars off of a fellow Head-fier, and they did sound good. However, the durability of these come into question. I had them for a few months, and I listened to them a week ago, and the right ear was just shot. No sound coming from it at all. I don't know why or how it happened, since it was in very good condition when I bought it. That's my only input on these, but I did enjoy the sound.
